- •
High power magnetic bucket-type arc plasma source for the VEST NBI system is developed with modifications based on the prototype plasma source for KSTAR.
- •
Plasma parameters in pulse duration are measured to characterize the plasma source.
- •
High plasma density and good uniformity is achieved at the low operating pressure below 1 Pa.
- •
Required ion beam current density is confirmed by analysis of plasma parameters and results of a particle balance model.
